Basic In-Frame Engine Overhaul Kit for Allis Chalmers B Series and CA Series Tractors

Description

When your vintage Allis Chalmers starts burning oil, smoking, or just doesn’t have the power it once did, it’s usually telling you the engine needs some serious attention. High hours, years of hard work, and normal wear have taken their toll on the pistons, rings, and cylinder walls. This basic in-frame overhaul kit gets you back to strong compression and reliable operation without the expense of a complete engine rebuild.

What You’re Getting

• Complete cylinder sleeves, pistons, rings, and pins for all four cylinders
• Valve-grind gasket set to seal everything up properly during reassembly
• Oil pan gasket to prevent leaks when you’re back up and running
• 3-3/8 inch standard bore with 3-7/16 inch overbore option for worn cylinders
• Everything you need for an in-frame rebuild without pulling the engine

Built for Real Farm Work

This kit serves the 125 cubic inch four-cylinder gas engines found in several generations of Allis Chalmers tractors. These engines powered the 1B, B, B125, B15, C, and CA series tractors that handled everything from cultivating corn to running belt-driven equipment. Whether your tractor spends its time on row crops, hayfields, or general farm chores, this rebuild brings back the power and reliability these engines were known for.

Made to Last

Tru-Power has been making engine rebuild components for decades, and they understand what it takes to handle farm conditions. The cast iron sleeves provide a fresh cylinder surface, while the pistons and rings are engineered to seal properly and last for years of hard use. The gaskets use materials that can handle the heat cycles and pressure changes of agricultural work.

Good to Know

This is a basic kit, so you’ll need to order engine bearings separately if yours need replacement. The standard bore works for most rebuilds, but the overbore option lets you clean up cylinders that have excessive wear or damage. Having a machine shop check your cylinder walls and deck the block if needed will give you the best results from your rebuild effort.
